IMPROVMENT IN' MUCILAG-E-'BOTTLES Thel Schedule referred to in theseLetters Patent and making part of the lame.

ATo all whom it mwy concern:

Be it known that I, BAL'rIs DE LONG, of Washington city, in the Districtof Columbia, have invented a certain new and useful Apparatus forGumming or Pasting Papers, Labels, and other similar articles, of whichapparatus the following is a full, clear, and exact description. 4

My invention is more particularly adapted to gumming the edges of paperswhich are intended to be pasted together or into a book. It may also,however, be adapted to pasting entire sheets, by increasing thedimensions of the respectiveparts.

The improvements herein claimed consist- First, in a novel method ofcombining, with a receptacle or reservoir for the paste or mucilage, agummingapparatus, mounted in an independent frame, which is fastened inthe reservoir bythe mere act of inserting it, and yet can readily beremoved therefrom when desired.

Second, in a novel method of combining a frame, a pasting-roller, and aguide, which clamps the paper and holds it upon the roller while beingpasted.

Third, in a novel method of combining the frame, the pasting-roller, andthe clamping-guide, with a gauge for adjustingthe width of the strippasted.

Fourth, in a novel method' of combining, with the frame andpasting-roller, a compressing-roller, rotating at an acute angle to theline of feed, to keep the paper against the gauge.

In the accompanying drawings, which show all my improvements embodied inone apparatus- Figure 1 represents a view in elevation of my improvedapparatus, showing two diierent modifications of my invention.

Figure 2 represents a similar view of the apparatus taken at iightanglesto iig. 1, and showing a front view of the device on the iightofg. 1.

Figure 3 represents a similar view of the other device.

Figures 4 and 5 are respectively plan views of the rollers detached,showing the angular arrangement'ofthe axes of the upper rollers.

To carry out the obj eots of my invention, I construct a reservoir orreceptacle, A, of metal, glass, or other suitable material, and ofproper forin, with a fianged opening, a, in its top. This opening l.make of an oblong or oval form, with an enlargement in its centre, asshown in figs. 1 and 2, for a purpose hereinafter explained.

The pasting-apparatus is mounted in a frame, A', by preference cut orstamped from sheetmetal, and of the form shown in figs-1 and 2,consisting of a strip, continuous on one side, andbent over in arectangular form at top and bottom, so as to form bearings for'therollers, and yet leave an open space between them onV one side.

The upper, or compressing-roller B, 1s mounted m a This roller isdepressed, when desired, by` a button, d, on this arm, but ordinarily isheld up by a spring, c2, in this instance, of rubber.

It is, however,- obvious that a metal spring might be coiled around theshank of the button, between it and the frame A', to hold up thisroller.

The l journals of the roller project through vertical slots, c, in theframe A', by which means the roller, while free to move vertically, isprevented from yielding laterally. The axis of this roller is arrangedangularly to that of the lower roller, as shown in g. 4, for

a purpose hereinafter explained.

' lhe gumming-roller B', is mounted in bearings in the lower part of theframe. I prefer tov make this roller in the form of a thin diskinternally, but with a broad rim or tread, so that while presenting thedesired amount of pasting-surface, its displacement shall be as small aspossible. The sides of the frame may be bent outward, above the axle ofthis roller, to prevent paste dropping from the roller and cloggi theframe.

I form slight grooves in the gumming-roller, either parallel ortransverse to its face, in order to retain paste enough to gum the sheetwhile passing under the compressing-roller, which, otherwise, I find byexperiment, tends to drive back the paste onvthe roller, and thusprevent its proper disposition on the sheet. The pasting-roller,however, need only be grooved on those parts acted upons by thepressure-roller.

In order to present the paper to the rollers, and to guide it properly,I form afclamping-guide, C, by bending a Wire'into a loop, and passingthe loop through holes in the' frame.

A wedge, f, iig. 1, is inserted into this loop, and

regulates the pressure of the loose ends of the Wire on the sheet, byopening or closing the loop.

A gauge, C', slides upon the wire clamp, to regulate the width of thestrip inserted between the rollers, and may be held in the' desiredposition in any proper, wellknown way.

The frame A' is provided with clips, a, which spring over the edges ofthe flanged opening a, and hold it firmly when inserted, and yet permitit to be removed v without detaching-screws or other fastenings.

The operation is as follows:

The operator depresses the compressing-roller by bearing on the buttond, with his left hand, until it presses on the pasting-roller. As soonas the rollers 'B B are in contact, he turns the compressing-roller thecompressing-roller is released, and its spring lifts it out of contactWith the pasting-rollcr, thus preventing paste from getting on bothrollers, and gumming both sides of the succeeding sheet.

The apparatus may be removed, when desired, and a wide brush, with itshandle inserted in a cover, may be used instead, when desired, or, byhaving two openings, both may be used at once.

In fig. 3, I have shown the apparatus as modified, by substituting anendless belt, E, for the pastingroller.

This belt passes over two rollers, D D. The upper roller, D, is mountedin proper bearings, and provided with a crank for driving it, thecompressing-roller, in this instance, being the one driven by friction,instead of the pasting-roller, as in iig. 2.

The lower roller turns in bearings, in strips e', fastened to a block,E', which is adjustable vertically in the frame by a slot and set-screw,f. This block acts s as a brace to the frame, and also serves to tightenthe belt.

The angular arrangement of the compressing-rollers, shown in figs. 4 and5, serves to draw the edge of the sheet inwards, and thus keeps the edgeof the sheet constantly pressed against the gauge, and thus insuresuniform worlL Vhat I claim as my invcnti0n,and desire to secure byLetters Patent, is-

l. The combination, with a mucilage-receptacle, of a gumming-apparatus,mounted in an independent detachablc-fr'aine, substantially as and forthe purposes specified. A

2.' TheV combination, substantially as set forth, of the frame, thepasting-roller, and the clamping-guide,l

3. The combination, substantially as set forth, with the frame,pasting-roller, and clamping-guide, of a gauge for adjusting the widthof surface gummed.

4. The combination, substantially as set forth, with the frame and thepasting-roller, of an angularly-arranged compressing-roller, whereby thematerial being gunimed is kept in contact with the gauge.
